I am working on Large office IDF with Ice storage. I am getting some warnings and severe errors that I wanted advice to fix:- error file:-

** Severe  ** CheckWarmupConvergence: Loads Initialization, Zone="BASEMENT" did not converge after 30 warmup days.
**   ~~~   ** See Warmup Convergence Information in .eio file for details.

The eio file says:-
